The 2 x 5 dBi, RP-SMA antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. The TL-WR842ND is compatible with 2.4 GHz Wi-Fi networks. Older routers have a more limited range than newer Wi-Fi standards. So, they are less suitable for larger homes or offices. Real-world TL-WR842ND router speeds are lower than its theoretical maximum speed.

WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
